2. Once you are in Audio MIDI Setup select the second option in the drop down list labeled "Properties For:" as shown below. Note that both of these options have the same name (at least for me they did) but one is input and the other is output.

5. IMPORTANT!!! Now that you've selected a 5.1 configuration MAKE SURE THAT EACH SPEAKER IS CORRECTLY CONFIGURED!!! Do this by clicking on each of the boxes. This should create a hissing sound from that speaker. If the sound comes out of the wrong speaker change it's speaker number until it is correct.

7. There you have it!!! This should allow your Realtec ALC850 sound card work in a 5.1 configuration. Now I've only tested this with a movie playing in VLC Media Player and I haven't yet tested it for music... so Good Luck!!!

I did this but it seems like two of my speakers don't work. I should say two of the channels don't work. Channel 3 and 5 make no hissing sound out of any speaker and I know for a fact that all my speakers work.

It also never saves my settings that I set in step 5.

You said VLC has 5.1 already in it? Does that mean it emulates it even for people with stereo or 2.1?

Well, basically it works, but in weird way - speakers configuration resets (actually speakers binding change in random way) each time new media is played, f.e. next audio track in DVD, next song in iTunes ect.

also only 48000 Hz is available and it can't be changed manually. this causes no sound in Quake3 :censored2:
